1. Kyle is using elimination to solve the system below and will first add the equations together.
4x – 2y = 18
-3x + 2y = -11
Which of the following shows the sum of the
two equations?
a. 7x = 29
b. x = 7
c. 7x = 7
d. x = -7.

c

step-by-step explanation:

at least i think its

area of part 1:

a1=base*height/2=(8+2)*(8-2-2-1)/2=10*3/2=15 ft^2

area of part 2:

a2=length*width=(8+2)*1=10 ft2

area of part 3:

a3=length*width=8*2=16 ft2

total shaded area : a1+a2+a3=41 ft2

total area of the reactangle : a=16*8=128 ft2

total area of the nonshaded region : 128-41=87 ft2

i found two solutions,   n = 2 • ± √3 = ± 3.4641
